Amsynths AM8171 Quad Sequential Switch


video upload by O.Z. Hall

"When Roland developed the System 100M they created a quad signal gate module, the 171, which also had a ton of multiples. The AM8173 module contains the same four signal gates built with modern components, and an onboard LFO clock, making it a very useful sequential switch, for both audio and CV signals.

SEM vs SEM - November 2023 edition


video upload by John Schussler

"The G-Storm Electro SEM VCF arrived the other day, and I figured I'd give it a listen in comparison to what, up to this point, I think is the best SEM eurorack module: the Studio Electronics SEM VCF.

(Spoiler alert: The G-Storm gives the SE a serious run for its money)

I've also thrown in the Bubblesound SEM20 and an AMSynths Obie XA. The Bubblesound is mostly SEM, but with some MS-10 bits grafted on that makes it more aggro. The Obie XA isn't a SEM at all, different chip, but is also modeled after an Oberheim filter so I figured I'd toss it in for contrast.

VCO is a Befaco Pony, first on saw then on square. Sequencer is a Clank Chaos. Envelope is Zadar.

Be forewarned: a lot of this video is me going back, and forth, and back, and forth, and back and forth between modules. Don't get seasick.

AM8122 Dual SVF (100M)


AM8122 BRIEF DEMO video upload by AMSynths





via AMSynths

"Overview The original Roland 100M (1978) has only one type of voltage controlled filter, 24dB low pass. This rather limits the range of sounds that can be created with the synthesizer and it is strange that Roland never ported the 703 2-pole OTA SVF into the 100M format. The AM8122 closes this gap and provides two 2-pole State Variable Filters in one 16HP module.

AMSynths Design The AS3320 chip is used to create the SVF, rather than the CA3080 OTA in the original 703 module. This is partly down to the limited PCB space for two filters and partly because the 3320 chip in SVF mode sounds very good, think Oberheim OBX. An alternative approach would be to build a dual Jupiter 6 SVF with AS3109’s, but this is tricky to achieve given the limited PCB space and we already produce a Jupiter 6 module – the AM8060 module.

The AM8122 circuit reuses the 2-pole SVF in the AM8325 and adds the BP mode and voltage controlled resonance. The third CV input is used as the Resonance CV input. The front panel design follows the Behringer 121 module with signal and CV input trimmers, frequency and resonance on 30mm sliders and green and red indicator LED’s.

Each filter has two outputs, with a slide switch selecting which filter output goes to which jack socket. The upper jack socket (OUT) can be set to either LP, BP or HP and the lower jack socket (REV OUT) follows the reverse (HP, BP, LP). This approach ensure the LED’s track the filter mode selected by the switch, whilst still providing individual outputs of each filter mode. The three signal inputs of the second filter are normalised to the outputs of the first filter (HP, BP and LP), so that the filter modes can be mixed together and filtered again!

Front Panels The panels use the same manufacturing process as the earlier AMSynths 100Mmodules, with a white silk screen over a dusty grey powder coated panel.

Outcome & Availability The module and panel were designed in December 2022. In 1Q23 the prototype PCB’s were debugged, with the revised LED drive and increased filter output levels so they are all the same (10V p-t-p). Production modules will be availble in 3Q23. The AM8122 will be the first AMSynths module to use SMD manufacturing processes (JLCPCB) for the PCB’s."

New AMSynths AM8109SE Low & High Pass Jupiter 8/4 Filters Eurorack Module



"This module is replication of the Low Pass and High Pass Filters from the legendary Roland Jupiter 8 and 4. This is a 2 and 4 pole OTA design that Roland first used in the Jupiter 4 in 1980, replacing a discrete version of the filter which took up more PCB space.

This is a warm sounding filter with smooth frequency control and a resonance that gradually increases up to full resonance, just before self oscillation, a sound very reminiscent of the early 1980's. The original Jupiter 8 filter did not self oscillate, and we have retained this configuration. However the customer can set the filter to self oscillate by adjusting a PCB trimmer on the rear of the module.

The difference between 2 and 4-pole modes is not dramatic, with the 2-pole mode providing a more gradual cutoff slope and silky sound. The high pass filter provides a gradual cutoff of low frequencies.

The AM8109SE is a new version of the 2010 AMSynths design, with slide potentiometers and a skiff friendly module depth of 35mm.

Eurorack Module: 14HP wide
User Manual: AM8109 Quick Start Manual

This module is an accurate reproduction of the Jupiter 8 low pass voltage controlled filter, using the AS3109 OTA chip in the filter core, as well as the high pass filter that uses an AS662 chip. The design has been updated to use modern components with high quality capacitors in the signal path. It delivers a very warm and smooth sound.

There are front panel sliders for adjusting the Cutoff Frequency and Resonance of the low pass filter, and level control of 3x control voltages (MOD, ENV and KYBD) and 2x audio signal inputs. The high pass cutoff frequency is adjusted using a rotary potentiometer with an original Boss coloured control knob.

There are five 3.5mm jack sockets at the base of the black anodised 2mm front panel;
2x audio inputs
3x control voltages
1x audio signal output
There is an audio output jack at the top right of the module. The slope of the filter can be switched between 2 and 4 poles using a small slide switch, and the envelope CV signal can be inverted using a second slide switch.

The module comes with a set of M3 mounting screws and washers, and a standard Doepfer power cable."

AMSynths SUPERBOOTH Module News - April 2022



"Getting Ready for SuperBooth 22

We are hard at work developing new modules for launch at the best synth show of the year - Superbooth 22. We will be announcing the red faced AM8101 filter [posted here], a replica of the low pass filter in the Roland SH-101, as well as the AM8102 SH-2 style filter [below].

The AM8109 and AM8060 Jupiter filters are being relaunched - 10 years after they were introduced, with Special Edition and slim 10HP versions. AMSynths will also be announcing SH-101, Jupiter 6 and 8 VCO's to pair with these filters alongside the current Jupiter 4 VCO and VCF."



This module is faithful replica of the filter from the legendary Roland SH-2 that was released in 1979. The AM81012 is a fantastic sounding 4-pole low pass filter with that unmistakable Roland filter sound in a narrow skiff friendly, Eurorack module.

The module use an Alfa Rpar AS622 chips in the filter core (BA662 clones) and high quality polpropylene filter capacitors. The design includes buffering Op Amps to interface to Eurorack modular levels. The filter does not have Q compensation but the signal level does not decrease dramatically with higher Q settings. The resonance is smooth and controllable into self-oscillation, and the filter will oscillate from 20Hz to 20kHz.

There are slide potentiometers (with LED's) for adjusting the Frequency Cutoff, and the frequency modulation from Keyboard, LFO and Envelope CV signals, There are rotary potentiometers for adjusting the mix between two audio inputs and Resonance. There is a small slide switch to select whether the envelope CV input is Normal or Inverted.

The AM8102 is hand built with high quality components, including Wima polypropylene capacitors, Alpha potentiometers, and TR808 style control knobs.

There are six 3.5 mm jack sockets on the front panel:
2x audio inputs
3x frequency CV inputs
1x audio output
The module comes with a set of M3 mounting screws and washers, and a standard Doepfer power cable.

Behringer's Cool Audio Clones the Roland BA662A


This one is in via Jose of sonicplug.com, spotted on Future Music Spain.

Per Behringer:

"Great news. Our sister company Coolaudio who designs mixed architecture semiconductors has just released the holy grail of synthesizer chips - a clone of the BA662A.

It is the THE chip responsible for the unique sound of so many classic synths.

Not only has Coolaudio cloned the BA662 “A” version, which is the highest specified version, they also managed to greatly improve noise performance and included even two chips in one packaging.

We’re beyond excited:-)"

The BA662 was used in the Juno-6/60/106, JX-3P and TB-303, Jupiter-4, and Jupiter-8.

via AMSynths:

"The BA662 is a custom made DC controlled variable transconductance amplifier (or OTA) that Roland had manufactured by Rohm from the late 1970’s and is now obsolete. There are two types of chip with different suffices; the A version has been selected for lower offset than the B version. They are further classified by gain/gm. The BA662B can only replace another BA662B, whilst an A can be used in either application.

To quote Roland from the 100M Service Manual: 'Color has great importance in circuits of some models'. However there is nothing mystical about the sound of the BA662, it is just a reasonable good OTA chip which is often carefully matched and selected."


Note Open Music Labs made a clone as well (last edited in 2014):

"They just don’t make IC’s like they used to, and is this case, they just don’t make them at all! So, we decided to bring the BA662 back to life, in all it’s Frankenstein glory. This is a direct replica (to the best of our knowledge) of the now obsolete OTA, made from well matched transistor pairs. It can be used as a drop-in replacement for most applications. So if you have an old synth or effects pedal that is no longer synth’ing or effecting, this just might be the cure...

The BA662 clone is a replica of the very rare BA662 OTA which was used by Roland in a number of their synthesizers and effects pedals from the 80's. The internal wiring of the BA662 was reverse engineered from an original part by applying external voltages and currents, and seeing how it responded. For example, you can find out how many transistors are at the top and bottom of the output stage by measuring the saturation voltages. From this it was found that they used Wilson current mirrors. Also, by measuring the current consumption under varying signal levels, the value of the emitter resistor on the buffer stage was found. A fair bit of the anaylsis was based on recollections from seeing a datasheet a long time ago, and the fact that OTA's have very similar topologies."

Behringer System 100 an AMSynths Joint Project?


See the update in this post. Some product sheets were added as well if you missed them.


NAMM 2020 - Introducing System 100 - Behringer Modular Synthesizer


Published on Jan 16, 2020 BEHRINGER

"Introducing eleven new Eurorack compatible modules – all of them authentic reproductions of original “System 100M” circuitry from 1975. With ultra-fat oscillators and creamy filters the sound became famous in the early 80s used by artists like Depeche Mode, Human League, Tears For Fears but also Vangelis, Tangerine Dream and even Aphex Twin.

If you’re into super-fat bass sounds, in-your-face leads or flowing soundscapes, definitely check them out! All modules are incredibly feature rich, have tremendous patching capabilities and a lot of them come with dual function, like:

- 112 dual oscillator with 3 waveforms, PWM and two sync modes
- 121 dual filter with 3-channel mixer per filter
- 130 dual VCA, again with dual 3-channel mixers
- 140 dual envelope has 3 outputs per ADSR plus a built in LFO that can be triggered and phase synced
- 173 gates module comes even with four gates that can switch audio and 6 quad buffered multiples
- 297 has a dual portamento controller plus two independent CV mixers
- 150 brings a ring modulator, 2 noise generators, syncable LFO and a sample and hold generator
- 172 module delivers a 6-step phase-shifter, an analog delay, an LFO and a gate delay
- 305 is an output module a four-band parametric EQ, a 4-channel mixer, line and separate headphone output and even a tuning oscillator
- 182 there is a powerful analog sequencer with either dual 8 steps or 1-16 steps and tempo, portamento and gate time controls
- 110 is a complete synth voice with VCO, VCA and filter in a single module

#NAMM2020"

Update: Word is this might be an AMSynths joint project. From their website:

"Behringer Partnership In June 2019 I joined forces with Behringer to design analog synthesizers that will be manufactured in China and sold to customer across the world. I am working on a number of projects which I will let Behringer announce when they are ready. AMSynths is continuing to grow with more Euro Rack modules being manufactured, as well as complete synthesizers like the SH05 and Jupiter One. In 2019 I started to restore vintage music gear, and you will see the repair stories in my Blog. I am also creating videos of my modules and the vintage synths that they emulate."


Update: some product sheet scans in in via Soviet Space Child and a note on one of the forums from Uli.



"I like to share with you the initial drafts of our M100 Eurorack Series.

These are 13 MID's or concept documents we create for every single product as part of our PLM (Product Lifecycle Management) process before we hand them over to our R&D departments for development.

We haven't decided yet which of these modules we will actually produce as it is important that we achieve a certain production volume.

As usual do we appreciate your valuable feedback which will give a better indication of validity of these products.

Thanks!

Uli"
